10. Waterfront, Charleston, S.C. — A federal court found the U.S. Army Corps of Engineers violated preservation laws when it approved the construction of new cruise ship terminals on the waterfront.

The National Trust for Historic Preservation took a look at 2013 and compiled a list of 10 historic sites saved and 10 historic sites lost last year.

The organization works to preserve historic buildings and areas in the United States, from parks to old post offices. It works in local communities and even has a stake in the controversial battle for, or against, Houston's own Astrodome.

Below is a list of sites that lost their historic status or were torn down, including a Texas landmark - the Univision Building in San Antonio. A mid-century build, the strucutre was the original home of the world-wide Spanish TV station - Univision - and was razed for condos in November.

Click through the slideshow for sites that were saved from demolition. See below for 10 that were not.

10 Sites Lost:

1. Prentice Women's Hospital, Chicago — After a long battle during which advocates urged preservation of the building, the way was cleared for the structure's demolition.

2. Cyclorama Center, Gettysburg, Pa. — The removal of the Cyclorama Center from the Gettysburg National Park is a loss for advocates of 20th century architecture, though it was supported by some preservationists under the grounds that it would improve the interpretation of the battlefield's history.

3. Chinese Hospital, San Francisco — Once the only medical facility available to the local Chinese community, the historic hospital was marked for demolition to make room for a new hospital center.
